Abstract
Using magnetometry and polarized neutron reflectometry (PNR), we have mapped the reversal processes of the antiferromagnetically coupled, hard/soft system, TbFeCo/[Co/Pd(tpd)}15, with perpendicular anisotropy. The magnitude of the exchange coupling within the [Co/Pd] layer can be tuned by varying Pd thickness. Since PNR is insensitive to moments perpendicular to the plane, a scattering geometry with polarization parallel to the scattering vector was used to isolate in-plane magnetization components and characterize the behavior of a domain wall near the bilayer interface. Consistent with predictions from a micromagnetic calculation, the characteristics of the domain wall vary with field and exchange stiffness in the Co/Pd.Citation
